Cirrus Logic (CRUS+3.4%) jumps after receiving an upgrade to Strong Buy from Feltl. The firm expects Cirrus to deliver a "beat and raise" FQ2 report (due on Oct. 29), and sees Apple's FQ4 report (due on Oct. 25) and the iPad Mini launch as positive catalysts. Cirrus obtains well over half of its revenue from Apple.
